1 answer:
The area of triangle ACD and ABC are 17 and 46.75 square units respectively
<h3>How to find the area of a triangle</h3>The formula for finding the area of a triangle is expressed as:
A = 0.5bh
where:
b is the base
h is the height
Area of the triangle ACD = 0.5DE * AC
Area of the triangle ACD = 0.5(2)(17)
Area of the triangle ACD = 17 square units
For the triangle ABC
Area = 0.5(BE)(AC)
Area= 0.5(5.5)(17)
Area = 46.75square units
Hence the area of triangle ACD and ABC are 17 and 46.75 square units respeectively

First you must distribute the 2x to the numbers inside the parentheses
(2x * x) + (2x * -1) = 3
- 2x = 3
To make this a quadratic equation you can solve bring the 3 over to the left side of the equation by subtracting it to both sides
- 2x - 3 = 0
Use the quadratic equation to solve this (image of the quadratic equation is below)
Remember that quadratic functions are set up like so:
That means that in this equation...
a = 2
b = -2
c = -3
^^^Plug these numbers into the quadratic equation and solve...
Keep in mind that +/- is ±
